Black launches two large volleys of piercing energy blades into the opponent, then gestures all of the blades to explode, causing a knockdown.

Black teams up with Zamasu to launch a slow-moving energy ball forward. Best way to pull this off is get your charge while standing, then jump and perform the rest of the command. Holding Up as they launch the energy ball steers it upwards, whilst holding Down steers it down.

Upon connecting with a forward dash, Black bursts into a Zamasu-assisted punching and kicking volley. If at any time during this volley you have another LV1 in stock and press 2 Punches, Zamasu will grab-hold of the opponent while Black charges up a Kamehameha, which he then launches straight at his helpless victim.

Black forcefully opens a dimensional rift (which can hit the opponent) from which a small army of Black clones emerge and then attack the opponent in a slashing cloud of death. Depending on the Punch button strength used, the clone army comes dashing in at different timings: with LP+MP they come out almost immediately, while with MP+SP it takes the longest. They'll always appear from behind Black, so even after you've switched sides with the opponent after creating the rift, they'll come from that side you're on.

A tip for executing this jackknife command: Charge DB, do HCF, HCB, jump and K at the same time or very closely. You may also press any up direction (Up, Up-Bwd and Up-Fwd all work).
If you're still having trouble; this move has an easy command config, which turns the command into QCBx2+any Kick.
Black teams up with Zamasu once more for this leaping slash attack. What happens after they connect with the opponent is anyone's guess... Depending if you're on LV1, 2 or 3 of the Godly Bar, Black will perform a Finisher at the end of the Divine Cross:
LV1 - Divine Punishment.
LV2 - Grotesque Wrath.
LV3 - Infinity Corruption.
